[coreboot] log2c, log2f and fms

unless I'm mistaken, the fms() function is equivalent to log2f(), but
the former is in asm while the latter is in C.
Generally, I'd like to have a libmath.c with all these mathematical
functions. Having a file only for log2 variants is not exactly the most
optimal tree organization.
How do we treat functions which have an optimized asm version but also
exist as C code?
- Weak functions?
- Macro tricks like #ifdef _HAVE_ARCH_LOG2C ?
- Kill the optimized asm completely?
